SEEDING-MACHINE.

Specification forming part of Letters Patent No. 44,241, dated September13, 1864.

To all whom it may concern:

Be it known that we, C. G. VANSTRUM and P. Gr. LINDBERG, both of RedWing, in the county ot' Goodhue and State ot' Minnesota,

have invented a .new and Improved Seedingments in broadcast-seedingmachines, which are so constructed that they can be used for ditferentkinds ot' seed by a simple change in the distributing' mechanism, orthat the discharge of seed can be temporarily suspended while turning ordriving from or to a cld.

The nature of ourinvention and its peculiar advantages will be readilyunderstood from the following,r description.

,A represents the seed-box, which is made of wood or any other suitablematerial in the usual manner. It is suspended from two axles orgudgeons, C, which are secured to its ends and have their bearings inthe wheels B B', as clearly shown in Figs. 2 and 3 of the drawings, anda draft-pole, D, serves to draw the machine over the iield or to thedesired place. This draft-pole extends through the seed-box, and itsrear end may serve to attach a harrow for the purpose of harrowing inthe seed as soon as it reaches the ground. The bottom of the seed-box isinclined toward the front part ofthe machine, and itis perforated with aseries ot' holes, a, large enough for 'the largest seed that may ever besown by the aid ot' this machine. The size or capacity of the holes amay be regulated by a slide,- I), which is mortised in the bottom ot'the seed-box, as clearly shown in Fig. 1, and provided with a series ofholes, c, corresponding in size and position to the holes a in thebottom, so that by changing' the position of the slide b the holes c canbe made to register with the holes a, or the solid portions of the slidemay be made to cover partly or wholly the holes a, andthe capacity -ofthese holes can be regulated. The slide b is operated by ahand-lever, d,which is pivoted to the front side ot' the box A audextends upwardthrough a mortise, so that it can be conveniently reached and operatedby the driver sitting on the cover of the seed-box.

The seed on being discharged from the box A drops upon thescattering-board E, which is hinged to the lower front edge ot' thehopper, its loose edge being suspended from a rope or chain, e, so thatit can be lowered or raised to suit circumstances, and thescattering-board is set to the desired inclination b v Winding the ropee round a pulley,f, which'is secured to a pin projecting from the rearside ot the box. This pin alsocarriesaratchet-wheel, g, which isrot-ated by means ot' a handle, h, and held in the desired position by apawl, t. By raising the pawl the ratchet-wheel and pulley can' be turnedbackward, the rope unwinds from thel pulley, and the loose edge of thescattering-board is lowered, and when the pawl is thrown in gear withthe ratchet-wheel the scattering-board can be raised to and held inanydesired position.

The hinges which securethe scattering-board to the box A are composedot' hooks j, projecting from the edge ot' the board and catching inholes in the lower ends of pendent levers lo k', which are pivoted tothe front side ofthe hopper-box, as clearly shown in Fig. 2 of the ydrawings. The lever k extends upward beyond its fulcrum, and it connectswith a tappet, l, the point of which is forced by a spring, m, againstthe scalloped edge of a circular flange, fn, secured to the inner sideof the wheel B. The front part ofthe tappet connects by a rivet or inany other suitable manner with an arm, o, which is rigidly attached to asliding toothed plate or stirrer, p. As the wheel B rotates thescalloped edge ot' the flan gc n produces a` reciprocating motion ot thescatterin g-board E and stirrer p, and the teeth of the latter, bysweeping over the seed-holes ca, prevent them lfrom clogging and insurea uniform discharge, and at the same time, by the shaking motionimparted to the scatteringboard, the seed is evenly distributed over theground.

If it is desired to discontinue the shaking motion of thescattering-board and stirrer, the tappet Z is pressed back by insertinga pin or stop in its front., so that the scalloped ange revolveswithout-coming in Contact with the point of the tappet.

This machine is very simple'in its construction. It can be made cheapand used for large or small seeds, and. all its parts are so oonstructedthat they are not liable to get ont of repair.

What We claim as new, and desire to secure by Letters Patent, is-

.Ihe adjustable hinged scattering-board E,

in combination with the pendent levers k, tap l pet l, scalloped flangen, stirrer p, and adjust able seed-slide b, all constructed andoperating in the manner and for the purpose herein shown and described.
